Cartalax- Summary
- Spermidine is a naturally occurring polyamine found in all living cells, with exceptionally high concentrations in wheat germ, aged cheese, and human sperm. It is the most studied autophagy-inducing dietary compound, shown to extend lifespan across multiple species and reduce cardiovascular and cognitive aging.
- Cartalax is a tetrapeptide bioregulator (Ala-Glu-Asp-Pro) developed by Professor Vladimir Khavinson for cartilage and connective tissue. It is tissue-specific for chondrocytes and cartilaginous structures, supporting cartilage matrix synthesis, slowing degenerative changes, and promoting joint longevity. It is used in the context of osteoarthritis, joint aging, and athletic cartilage preservation.
- Half-Life
- ~30–60 minutes, but gut bacteria produce it continuously; supplementation raises tissue levels over weeks
- Short (minutes); gene-regulatory effects are sustained
